Memory Leak in ImageMagick TIFF Encoder

Publication date: 2026-07-15

Last updated on: 2026-07-15

Assigner: VulnCheck

Description
ImageMagick before 7.1.2-26 and 6.9.13-51 contains a memory leak in the TIFF encoder when an invalid tiff:tile-geometry is specified. Supplying malformed tile geometry parameters causes allocated memory not to be released, which can lead to increased memory consumption.

Executive Summary

This vulnerability is a memory leak in ImageMagick's TIFF encoder. When an invalid tiff:tile-geometry parameter is provided, the software fails to release allocated memory properly. This leads to gradual memory consumption increase during processing.

Impact Analysis

The impact is limited but could cause system slowdowns or crashes due to excessive memory usage. It requires local access and user interaction to exploit, making it less likely for remote attacks. The main effect is reduced system availability.

Detection Guidance

To detect this vulnerability, check the installed version of ImageMagick on your system. Run the command 'convert --version' or 'magick --version' to see the version. If the output shows a version prior to 7.1.2-26 or 6.9.13-51, your system is vulnerable.

Mitigation Strategies

Upgrade ImageMagick to version 7.1.2-26 or later for ImageMagick 7, or to version 6.9.13-51 or later for ImageMagick 6. This will patch the memory leak vulnerability in the TIFF encoder.

Executive Summary

This vulnerability is a memory leak in ImageMagick's TIFF encoder. When an invalid tiff:tile-geometry value is provided, the software fails to release allocated memory properly. This leads to increased memory consumption over time.

Impact Analysis

The primary impact is resource exhaustion. An attacker could exploit this to consume excessive memory on a system running vulnerable ImageMagick versions, potentially causing performance degradation or system instability.

Detection Guidance

To detect this vulnerability, check the installed version of ImageMagick using the command: convert --version or identify --version. If the output shows a version prior to 7.1.2-26 or 6.9.13-51, the system is vulnerable. Additionally, monitor memory usage during TIFF image processing tasks for unexpected increases.

Mitigation Strategies

Immediately update ImageMagick to version 7.1.2-26 or later for the 7.x branch, or 6.9.13-51 or later for the 6.x branch. If updating is not possible, restrict access to ImageMagick commands and avoid processing untrusted TIFF files until patched.
